Display device and tiled display device including the same

Abstract

A display device comprises a substrate including emission areas, and light blocking areas adjacent to the emission areas, a thin film transistor layer comprising a thin film transistor disposed on the substrate, and a connection line electrically connected to the thin film transistor, a light emitting element layer disposed on the thin film transistor layer and comprising light emitting elements corresponding to the emission areas, an encapsulation layer overlapping the light emitting element layer, and a pad portion disposed on the encapsulation layer and in electrical contact with the connection line through a contact hole in the encapsulation layer.

Description

CROSS-REFERENCE TO RELATED APPLICATION(S)[0001]This application claims priority to and benefits of Korean Patent Application No. 10-2020-0082331 under 35 U.S.C. § 119, filed on Jul. 3, 2020 in the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference.BACKGROUND1. Technical Field[0002]The present disclosure relates to a display device and a tiled display device including the same.2. Description of the Related Art[0003]With the advance of information-oriented society, more and more demands are placed on display devices for displaying images in various ways. For example, display devices may be employed in various electronic devices such as smartphones, digital cameras, laptop computers, navigation devices, and smart televisions. A display device may be a flat panel display device such as a liquid crystal display device, a field emission display device and an organic light emitting display device. Among the flat panel display devices, in...

Benefits of technology

[0005]Aspects of the present disclosure may provide a tiled display device capable of removing a sense of disconnection between multiple display devices and improving a sense of immersion in an image, by preventing the recognition of boundary portions or non-display areas between the display devices.

[0027]In the display device and the tiled display device including the same according to embodiments, light emitted from a light emitting element layer may be reflected by a reflective member and transmitted to the front of the display device through a substrate. A pad portion may be disposed on an encapsulation layer at the edge of the display device. Each of the plurality of display devices may include the pad portion disposed at the rear thereof, thereby minimizing a size of the non-display area of the display device. Accordingly, in the tiled display device, by minimizing the gap between the plurality of display devices, it may be possible to prevent a user from recognizing the boundary portions or the non-display areas between the plurality of display devices.

Problems solved by technology

In case that the display device may be manufactured in a large size, a defect rate of the light emitting element may increase due to an increase in the number of pixels, thereby deteriorating productivity or reliability of the display device.
